It's too... slow
I've been playing this for almost a week now and this is my honest review about the game, I really don't like how at the start I didn't have any gems nor coins to help me progress, keep in mind that the tutorial kept on making the player (me) buy more and more stuff without rewarding him by giving some of it back (like how if you buy a power up you can keep it in your inventory and use it whenever you need it), and when you finish from doing a puzzel you get around 100 coins max and the whole game is just orianted around watching a lot of ads just to be able to continue forward or to do anything, not to mention that the missions/daily objectives are already hard to do and discouraging... Overall just a shame, its just like how everyone says, its just a money grab, all ads and promotions and the gameplay is super slow and not rewarding enough, I feel like I would have to play for months just to be able to upgrade a perk or two because of how the puzzles require you to get 2000 more points every time you finish one and you don't have money to upgrade anything (because I personally started without anything), the gameplay is good and if there are a lot of characters to meet and unlock then you would at least be able to progress fine without losing interest in the first 2 days of playing the game without being able to advance further...
